Face

Class

Description:
A bounded face of a 3d solid or open shell.

Remarks:
Faces are defined by surfaces (Surface) bounded by edge loops. The surfaces provide natural UV parameterization to the faces.

Face Class Members:

Name	Description	Inherited From
Area	The area of this face.
EdgeLoops	A collection of edge loops. Each edge loop represents one of the closed boundaries of the face.
GraphicsStyleId	The ElementId of the GeometryObject's GraphicsStyle (Inherited from GeometryObject )	GeometryObject
HasRegions	Identifies if the face contains regions (which can be created, for example, by the Split Face command).
Id	A unique integer identifying the GeometryObject in its associated non view-specific GeometryElement. (Inherited from GeometryObject )	GeometryObject
IsCyclic	Indicates whether the underlying surface is periodic in the specified parametric direction.
IsElementGeometry	Indicates whether this geometry is obtained directly from an Element. (Inherited from GeometryObject )	GeometryObject
IsReadOnly	Identifies if the object is read-only or modifiable. (Inherited from APIObject )	APIObject
IsTwoSided	Determines if a face is two-sided (degenerate).
MaterialElementId	The element ID of the material from which this face is composed.
OrientationMatchesSurfaceOrientation	Returns true if this face's orientation matches the orientation of the face's surface, false if they have opposite orientations.
Period	The period of the underlying surface in the specified parametric direction.
Reference	Returns a stable reference to the face.
Visibility	The visibility. (Inherited from GeometryObject )	GeometryObject

Name	Description	Inherited From
ComputeDerivatives	Returns the first partial derivatives of the underlying surface at the specified point.
ComputeNormal	Returns the normal vector for the face at the given point.
ComputeSecondDerivatives	Returns the second partial derivatives of the face at the specified point.
Dispose	Causes the object to release immediately any resources it may be utilizing. (Inherited from APIObject )	APIObject
Equals	Determines whether the specified Object is equal to the current Object . (Inherited from GeometryObject )	Object
Evaluate	Evaluates and returns the XYZ coordinates of a point at the indicated UV parameterization of the face.
GetBoundingBox	Returns the UV bounding box of the face.
GetEdgesAsCurveLoops	Returns a list of closed curve loops that correspond to the edge loops of the face. Curves in each curve loop correspond to individual edges.
GetHashCode	Gets the integer value of the geometry object as hash code (Inherited from GeometryObject )	GeometryObject
GetRegions	Gets the face regions (created, for example, by the Split Face command) of the face.
GetSurface	Returns a copy of this face's surface.
GetType	Gets the Type of the current instance. (Inherited from Object )	Object
Intersect(Curve)	Calculates the intersection of the specified curve with this face.
Intersect(Face)	Calculates the intersection of the specified face with this face and returns the intersection results.
Intersect(Curve, IntersectionResultArray)	Calculates the intersection of the specified curve with this face and returns the intersection results.
Intersect(Face, Curve)	Calculates the intersection of the specified face with this face and returns the intersection results.
IsInside(UV)	Indicates whether the specified point is within this face.
IsInside(UV, IntersectionResult)	Indicates whether the specified point is within this face and outputs additional information about the point location.
Project	Projects the specified point on the face.
ToString	Returns a string that represents the current object. (Inherited from Object )	Object
Triangulate()	Returns a triangular mesh approximation to the face.
Triangulate(Double)	Returns a triangular mesh approximation to the face.
